It slots into the same battery bay and connects to the same charge circuit as the original cell pack. Capacity is 1800mAh (21.6Wh) — matching the OEM specification from product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDV700 and FV Series compatibility:\u003c\/strong\u003e\n    These models share a common 12V battery architecture, the same physical connector, and the same BMS handshake protocol — which is why a single cell pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the DV700 platform. The BMS accepted the cell chemistry, completed its learn cycle, and reported correct state-of-charge on the device display after one full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interruption. Medical devices in this class run BMS verification at startup — cutting power mid-sequence triggers a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DV700 reports low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DV700's charge management circuit stores a state-of-health baseline from the previous cell pack. A new Ni-MH cell has a different internal resistance profile — the BMS reads this as a mismatch and flags low battery even when the cell is at full capacity. This clears after one complete charge-discharge cycle. The BMS recalibrates its threshold once the new cell completes that first full cycle at 12V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If the pack voltage has dropped below the BMS recovery threshold — typically around 10V for a 12V pack — the device will not boot. Place the battery on charge for a minimum of 30 minutes before attempting to power on. If the device still does not respond, leave it on charge connected to mains for a full charge cycle before attempting power-on again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381468069978,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381468102746,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381468135514,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/curtis-mathes-dv700-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
